Abstract

La presente invención se refiere a eyector para neutralizar una solución acuosa alcalina con C02 en forma de gas, el eyector incluye una sección de entrada convergente que promueve una umento de la velocidad de la solución transfiriéndola de una sección de diámetro mayor a otra de diámetro menor, una sección intermedia y una sección de salida divergente, caracterizada porque la sección intemedia incluye un tubo que tiene una pluralidad de micro-aberturas a través del mismo, una pluralidad de agujas, también extendiéndose a través del tubo, los micro-agujeros y las agujas están adaptadas para inyectar C02 en forma de gas en diferentes puntos alrededor y dentro del flujo de líquido, por lo cual la reacción del C02 líquido se lleva a cabo en la sección intermedia y en que en la sección de salida divergente ocurre una mezcla de régimen turbulento entre la fase líquida y el C02 en forma de gas, la reacción de neutralización es complementada por la mezcla.
